He said all the recipes at the store were from his late mother, Aroha Poipoi, who originally sold her food at the Kuirau Park markets.
"What we are doing is taking that food and putting it into this environment," he said.
"That is why we branded the food Aroha Maori Food. It acknowledges her history and it is her recipes."
Mr Poipoi said anyone could go into the store and buy Aroha products like rewena bread or chocolate brownies.
The feature food on offer at Kiwi Kai includes hangi and rewena bread, which is used in their burgers.
He said rewena bread was made using potatoes. Mr Poipoi said the store was owned by five friends and relatives including himself, Maurice Pomare, Rangi Pomare, Charlotte Pomare and Moe Tansey.
He said he hoped tourists would also be attracted to try the food, as well as Kiwis.
Kiwi Kai's opening hours include 10.30am to 7.30pm Tuesday to Friday and 5pm to 7.30pm on Saturday.
